In subject area: Computer Science A clock interrupt is a type of interrupt that occurs periodically in a system, but can be disabled to prevent interruptions during critical sections of code. AI generated definition based on: DSP Software Development Techniques for Embedded and Real-Time Systems, ...
You can easily end up with more devices in your computer than there are inter- rupts. If a module requests an IRQ at initialization, it prevents any other driver from using the interrupt, even if the device holding it is never used. Requesting the interrupt at device open, on the other...
• Case 1: Apollo Guidance Computer (AGC) - first recognizably modern embedded system, used in real-time by astronaut pilots to collect and provide flight information, and to automatically control all of the navigational functions of the Apollo spacecraft. First moon landing - flood of ...
An architectural order is the separation of functions (by walls), additionally specialization in architecture means everything allocated in its place/environment (toothpaste in the bathroom). This approach does not fit the everyday reality of global syncretism and simultaneity anymore. Also the ...
The FastWake system architecture is compatible with existing RDMA applications, operating systems, and hardware. We added the ODPI preload library as a shim layer in the user space. We updated the OFED kernel modules to shorten the kernel path and added a “switch_to“ system call to implement...
In 2000 - when I was helping the Computer History Museum restore their 1620 by designing and building a hardware peripheral emulator - I had the honor of discussing it with the late Joe Crespo, an IBM engineer from the San Jose group that brought up the prototype in 1958. He told me tha...
model, in a FPGA architecture. Finally, in Section 7, conclusions are presented. 2. Difficulties of the traditional model in real-time systems Since the traditional model of interrupt handling is strongly supported by hardware, it yields a fast ...
1. An improved method, performed by a computer system executing a set of program instructions referred to as a transport-mechanism program, of processing an interrupt, wherein (i) said interrupt is generated by a user program executing in an operating environment of said computer system, (ii)...
A method and apparatus for reducing the number of interrupts issued by a first device to a second device in a computer system. A delay interval is specified to the first device, the delay interval ind
computer 150. In order to couple integrated video processing system 100 to host computer 150 by way of host bus 140, printed circuit board 162 may be inserted into slot 154 of back plane 152. Also inserted into back plane 152 is printed circuit board 155 upon which host computer 150 is ...
